Equinox September 2012

The Earth polar coordinates turn in a circle to the central Sun and in
less than two weeks will turn through the circle of illumination as it
has done two for every orbit over the billions of years it has been in
existence -

Apart from the degree of inclination,the planet Uranus is doing the
exact same thing -

I don't know why people do not see why the Earth has a largely
equatorial climate when all the information is put together and
especially the simple imitation analogy which explains two separate
axis for two simple motions,one daily rotational and the other
orbital,for without this information it is impossible to discuss
climate or weather.

A society without astronomy has really nothing to say.

I don't understand the subject line: aren't the equinoxes in the spring
and fall, not summer?

Huh? Fall begins with an equinox in September. So what is the problem?

Blush... I misread "Summer" for "September". And I don't even have a
trace of dyslexia to blame it on.

No problem - an equinox for an astronomer is when the polar coordinate
turns to a position that is at a right angle to the central Sun,for a
magnification enthusiast it is something about the Sun crossing a Ra/
Dec convention,fine if that is all they can manage but exceptionally
poor when planetary dynamics is responsible for the equinoxes and
solstices.

Astronomy is not really a magnification exercise for the middle
class,it belongs to all humanity and especially students who never
learn so many of its principles,insights and methods and most of which
are within reach of teenagers and interested adults.The creation of
the calendar system using the annual return of a star and the great
flooding of the Nile is one such lesson in astronomy and from there on
to the great timekeeping system we use today in tandem with the daily
and orbital motions of the Earth.For some awful reason the entire
system is rejected for little more than a poor judgment and the
dominance of mathematicians who have a stranglehold on astronomy and
terrestrial sciences.

Since you are so keen on the ideas of Greek philosophers you should accept
that this is about people like you.
From Plato's Timaeus/
"innocent light-minded men who think that astronomy can be learnt by
looking at the stars without knowledge of mathematics will become birds "
(in the next life).
In your case presumably an oriole.

You don't need mathematics to enjoy astronomy no more than you need
mathematics to drive a car and interpret speed,bends on the road and
how and when to overtake another vehicle as these things come
naturally and while it is true that you need talent to drive at a
level of F1 ,I believe that these drivers begin with go karts.The
astronomical equivalent is learning how the calendar system is put
together using an annual meteorological event,the appearance of a star
and how many days it takes that star to return from behind the glare
of the Sun and unfortunately none of you can get into first gear
here.Even to the Greeks,the golden age of astronomy was thousands of
years older as they encountered Egyptian astronomy and people have
come to accept that astronomy on the Western European isles is much
older still so much like many here restrict astronomy to magnification
and nothing else,so they also limit historical perspectives in a way
the old Greek astronomers never did.

As the biggest single user of 21st imaging to promote a method or an
insight there is no need to fuss too much about representing cause and
effect on paper as the older astronomers once did,anyone with a talent
for interpretation can simple discover a common denominator in all
planets and apply them to appropriate cause and effect.The fact that
the Earth turns twice to the central Sun,it turns 4 times as a
component of its orbital motion while turning 1461 times in its daily
cycle can be drawn down from watch Uranus do much the same thing
albeit with its own proportion between rotations and orbital cycles -

You once could hold a technical argument but like so many others it
seems you have descended into being a nuisance in which case you can
have the luxury of saying whatever you want,my business is to find
people who can talk about the new approaches to astronomy using modern
imaging rather than being dragged down into a false and flawed late
17th century perspective that is going nowhere.This is a shame as you
have remained in this forum as it has transformed itself from being a
middle class magnification exercise into a source of information to
the wider community where lots have changed as they have adapted and
adopted many of the issues brought up here in this forum,some with
more success than others.
